Re: Westinghouse L1928NV

While there was annoying occasional flicker I heard no hissing.
And never went into protected mode.
That all started after I resoldered the bulb.

I have a DMM and an ESR. I will recheck next week when I have some free time.

The dim bulb remain dims when I swap connectors so I am thinking that rules out one of the inverter transformers. The dim bulb is NOT the one I resoldered. I suppose I should dissect that connection next.

Thnak you for your comments. I will report back soon.

Re: Westinghouse L1928NV

A snap to disassemble now. But separating the leads made no difference.
About all I could observe is that 1 tube is ever so slightly dimmer than the other 3. Swapping leads did not change which tube was dimmer.
[The dimmer tube is not the one that had the broken lead.]
The connections "sounded" good [no hiss at the joint] but since they are buried in a block of rubber, to go further would be destructive.
The "hum" comes from [one of] the inverter transformer[s].
Might that be enough imbalance to set...

19 inch monitor began to flicker slightly. Annoying.
I replaced 4 CapXon capacitors that were buldging with Rubycons.
Still had the slight flicker. No hissing.

I wiggled the Chi Mei branded screen apart.
One lead of the CCFL immediately fell off.
I assume this was the problem. Bulb not blackened so I made a splint for
the short stub on the CCFL and resoldered the lead.

Reassembeled but no joy.
Unit fires up, the inverter hisses and goes to protected mode in a few seconds.

Testing individually, the bulbs light...
